AUTOMATIC SOB'I'IER FOR JEULNGH PRESSES,

Application filed November 1, 1924.

This invention relates to a sorting device for punch presses forautomaticallyseparating the stampings from the scrap discharged from thepress and deliver them to separate collection receptacles during theoperation of the press.

One object of my invention is to make the sorter a single andinexpensive fixturev Fig. 1 is a side view of a punch press equippedwith a sorter of my invention;

Fig. 2 is a front view of the press so equipped p Fig. ,3 is an enlargedtop view of the sorter removed from the press;

Fig. 4 is a side view of the same;

Figs. 5 and 6 are vertical sectional iews on lines 54-5 and 64-6,respectively, of Fig. 3;

Fig. 7 is a perspective view of ,a flanged ing; a

8 is a like view of the scrap center he eoi- The punch press shown inFigs. 41 and 2 is of the open back, inclinable type. It has a supportingbase 1 and an upper part 2 on which are mounted the operative parts ofthe press, including a sliding ram or cross-head 3 connected by a rod 4with the operating shaft ,5, on which is a combined fly-wheel anddriving pulley 6. The crosshead 4 carries a punch 7 coacting with a die8 at the table of the machine, as usual in structures of this character.

The sorter of my invention comprises two sheet ,metal gutters .ortroughs 9 and 10, one above the other and combined to form a single unitor fixture. In the form shown in the drawings, the lower trough alias afiat bottom wall 11 andupright ,side walls 12 12. Said trough 9 isprovided with an outlet chute 13 at its trout or outerend Serial No.747,309.

and at one side of the same. The flat bottom wall of the chute 13 is acontinuation of the bottom wall 11 of the trough while the side walls14, 15 of the chute join the respective side walls 12, 12 of the troughand are at an angle or inclination thereto with the front wall 14 of thechute extending across the outer end of the trough, as shown in Fig. ,3.

The upper trough 10 is arranged above the bottomv wall 11 of the lowertrough 9 and,

being in Zigzag form, extends back and forth across the trough 9 fromone side wall 12 thereof to the other, as shown in said Fig. The uppertrough 10 has a flat. bottom wall 16 and upright side walls 17, 18, thelatter being in contact with the side walls 12, 12 Where the trough 9meets the same. ,At these places of contact, the walls are securedtogether for supporting the trough 10 in the other one and abov itsbottom wall 11, as described.

The outer end of the upper trough 10 is at the side of the deviceopposite the chute l3 and extends through the front wall 14 of the lowertrough, as shown, to provide an outlet chute 19 for said: upper trough.

The portion 20 of the side wall 18 at the inner end of the trough 10extends at an inclination inward to makethe inlet end of said troughhopper-shape, as shown in Fig. 3. i

The angular portions a, a of the side walls 17, 18v extend across thetrough 9 and are provided with elongated, relatively narrow slots 21,there being one slot in ,each angular portion and extendingsubstantially the full length thereof. These slots 21,21 extend abovethe bottom wall 16 and have their lower edges flush therewith foropening the upper trough {to thelower one.

Extending above the troughs 9, 10 .are up rights 22, 22 secured to theside walls 12, 12

ot the lower trough 9 adjacent its rear end, as shown in Figs. 3 to 5. Across-bar 23 extends between the ,upper ,ends of these uprights and theupwardly bent ends of said bar are pivoted to the uprights 22 ;byhorizontal pins or trunnions 24, 24. A rod 25 extends across said bar 23from the rear end of thedevice, and is secured to saidhar by aloop-shaped strap 26.' A rubber loll-1nper 27 is carried ;by the rod 25at its forward enchand strikes against a bridge piece .011,

in position with'its troughs 9 and 10 opening upward and with the innerend of the bumper rod below a lug or projection 29 (Fig. 1) on the rearside of the cross-head orram 3 at the punch 7. The chutes 13 and 19 atthe outer end of the sorter are over their respective collectionreceptacles 30, 31, as shown in Fig. 2.

In stamping out sheet metal rings with turned up flanges, such as areused as gromets for holding together the sheet metal and asbestos layersof cylinder head gaskets, the flat metal parts out from the center ofthe rings are in the form of discs and are treated as scrap from theoperation. Heretoi ore the rings andcenters were discharged from thepress into one collection receptacle,

thus mixing the rings with the scrap and, both being relatively smalland or thin gauge, made separation a troublesome and expensive job,especially as the parts tend to adhere by reason of oil being on them.

The sorter of my invention separates these parts and deposits them intoseparate receptacles. The rings are indicated by 32 in Fig.

i 7, and the scrap centers by 33 in Fig. 8.

These discs in the punching operation are fed up through a bore 3& (Fig.l) in the punch and are discharged therefrom at its upper end through anoutlet slot 35. This slot discharges the discs into the inner orentrance end of the upper trough 10. The rings 32 come 01E the die 8 andalso drop into the trough 1O inasmuch as its bottom wall 16 extendsclear across the lower trough 9 at such end.

' As the punch 7 is reciprocated, its lug 29 in moving against and awayfrom the inner end of the rod 25 causes thebumper or vibrator 27 to giveintermittent blows or taps on the sorter and jar the same continuallyduring the operation of the press to cause the rings and centers toslide down the trough 10. The centers 33 slide fiatwise down the trough10 and on reaching the slots 21 pass through and drop into the lowertrough 9, from which they are discharged into the receptacle 30, thusbeing separated from the rings 32 which are too wide for the slots 21and remain in the upper trough 10 to be discharged therefrom into thereceptacle 31. Each angular portion a of the trough 10 has its slot 21,so that in case some of the discs pass the upper slots they will in timepass into the lower trough 9 through the lower slots. 'l Vith the trough10 above the bottom wall 11 or the trough 9, the former does notinterfere with the discs sliding down the trough 9 from any slot 21.

This sorter may be equally as well used for other stampings havingflanged rings and fiat centers, such as produced in making sheet metalrings for combined sheet metal and asbestos gaskets. I do not wish tohave my invention limited either to the particular product described orto the details of structureshown and described, as the latter may bevariously changed and modified without departing from the spirit andscope of my invention.

I claim as my invention i 1. A sorter adapted to be applied to a punchpress and having two downwardly inclined troughs with outlets at theirouter ends, said troughs being connected and arranged one above theother with the upper trough disposed to initially receive both thestampings and the. scrap as discharged from the press, said upper troughhaving slots therein for the passage only of the scrap from the upper tothe lower trough, and means carried by the sorter for jarring the samefor progressing the scrap and stampings down the troughs and disposed tobe actuated by a moving part of the press.

2. A sorter adapted to be applied to a punch press and having twodownwardly inclined troughs with outlets at their outer ends, saidtroughs being connected and arranged one above the other with the uppertrough disposed to initially receive both the stampings and the scrap asdischarged from the press, said upper trough extending zigzag across thelower trough and having slots in its angular portions for the passageonly of the scrap from the upper to the lower trough, and means carriedby the sorter for jarring the same for progressing the scrap andstampings down the troughs and disposed to be actuated by the ram of thepress.

3. A sorter adapted to be applied toa punch press and having twodownwardly inclined troughs with outlets at their outer ends, saidtroughs being connected and arranged one above the other with the uppertrough disposed to initially receive both the stampings and the scrap asdischarged from the press, said upper trough having slots therein forthe passage only of the scrap from the upper to the lower trough, ananvil carried by the upper trough, and a bumper carried by the sorterabove the upper trough and disposed to be actuated by the ram of thepress to deliver blows against said anvil to jar the sorter in theoperation of the press.

4. A sorter adapted to be applied to a punch press and having twodownwardly inclined troughs with outlet spouts at their to deliver blowsagainst a part of the upper trough to the sorter in the actuation of theopposite end of the rod by the ram of the press.

5. A sorter adapted to be applied to a punch press and having twodownwardly inclined troughs with outlet spouts at their outer ends, saidtroughs being arranged one above the other with the upper troughdisposed to initially receive both the stampings and the scrap asdischarged from the press, said upper trough having slots therein forthe passage only of the scrap from the upper to the lower trough,upright members fixed to the sorter on opposite sides thereof andextending above the upper trough, a cross-bar extending between saidmembers atthelr upper ends and pivoted thereto, a rod exthe opposite endof the rod by the ram of the press.

6. A sorter adapted to be applied to a punch press and having twotroughs with flat bottom and upright side walls, said troughs havingdiverging outlet spouts at their outer ends and arranged one within theother with their side walls secured together and their bottom wallsvertically spaced apart, the upper trough being Zigzag and extendingacross the lower trough trom one side wall thereof to the other withelongated slots in the lowermost portions of the upright side walls ofsaid upper trough and flush with the bottom wall thereof, and a membercarried by the sorter and disposed to be actuated by the ram of thepress for delivering blows to the sorter for jarring the same in theoperation of the press.

In testimony that I claim the foregoing as my invention, I affix mysignature this 22nd day of October, 1924.
